It will.
Ouster has begun implementing Lidar technology in Tennessee, Utah, and a few other locations.

You're welcome

You can tell a lot about human nature by watching their behavior at a traffic light.

Slime molds will do anything for oatmeal. Just thought that bit of trivia deserved appreciation.

Slidell is the worst. I feel like every light here either turns red when cars get close to it or it’s only green for 3 secs. Not surprising for this shithole and the idiots that work for the gubment here.

You’ve made literally no reference to them.

change the light when there are no cars on the cross street but a long line backed up waiting for the regular light cycle to change

I think it would be extremely difficult…
It is not just a matter of timing one light to the next, as that would be simple. I’m sure they have to take overall traffic flow as well as everything from rush hour to the middle of the night.
I agree….AI is ideally suited for things like traffic light timing. However, if it takes everything into consideration, it may not yield the results that you think it will.

The lights in Baton Rouge are perfectly synchronized. They’re synchronized to force every car to stop at every light, but synchronized nonetheless.

It's difficult because of the sheer quantity and diversity of variables. If you only consider one intersection, you can tune and tweak it, take every variable into account, and get it "perfect" so that average wait times are minimized in all directions at all times.
But then add a second intersection where some of the same traffic interacts with both. Already it is likely impossible to optimize wait times at both intersections simultaneously. The best you can do is balance them to optimize the two-intersection system. And the problem gets harder exponentially as you scale up to hundreds of intersections. Each individual intersection will be pretty far from optimal in order to optimize the system as a whole.
And to truly optimize a whole city, the AI would need navigation data from every vehicle to avoid potential congestion. This might require an entire data center's capacity to keep up with it all if using AI.

But a central controller (or clustered decision-maker) would still be required to coordinate things, otherwise each intersection would compete to optimize itself at the expense of the system as a whole.

This seems to be a decent solution, but you probably know better than me...
The edge computer only sends lightweight METADATA back to the central server. Instead of sending a gigabyte of video, it sends a tiny text packet that essentially says: "Northbound lane has 5 cars, average speed is 35 mph, pedestrian waiting to cross."
Because of EDGE AI, the central city server doesn't need to be a supercomputer. It just acts as a dashboard collecting tiny status updates and coordinating the broader grid.

I didn't realize the were controlled by a dude in a booth hitting switches. Seriously, I think get synced every so often, but after awhile it gets off the timing.
I think, if you are on a road like Airline, if you hit a red light, once it turns green it was synced so that if you.. Lets say turn on airline from Bluebonnet and going to north to get on the old bridge, you would not hit another red light. but I think it was based on driving a certain speed.. likely the speed limit so if someone goes 15 mph faster they will get to a red light faster and have to wait for it to turn green which then makes it pointless to drive faster.

You don't think Waze has this information?! Sign a contract with Google/Gemini.
In Baton Rouge, we don't need a 2 minute stop of Perkins for Quail Drive, especially on the weekends. NO ONE IS THERE. NO ONE IS EVER.THERE. Same for all of downtown baton rouge too.
All lights at least need motion sensors on non dominant lanes

No, they do not have knowledge of unpredictable future traffic future movements. Would be pretty nifty if they did. quote:

There are sensors all over that intersection
